ABB Advant® Controllers
Advant OCS with MOD 300 softwareprovides an open systems framework that
unites functions and people throughout
the organization, resulting in productivity
increases and profit margin improvements.
As part of the Advant OCS portfolio,
Advant Controllers combine high
processing capacity with flexible
software to create a powerful control
system environment.
Advant Controllers benefit from a global
database and three powerful control
languages: CCF, TCL and TLL. Existing
MOD 300 6000 Series and SC Controllers
can all co-exist on the same Distributed
Communications Network (DCN) as
Advant Controllers and share data in
a seamless manner.
An Integrated Architecture
All MOD 300 software is designed to work
together as an integrated system. The
Global Database ensures that information
needs to be entered only once and that
multiple copies of the same information
do not reside in different subsystems—
information resides in only one location.
Application programs such as control
algorithms, operator interface and
information management software all
use the Database Manager to act upon
one set of data.
Throughout the entire system, all informa tion is identified by tag name. Unlike
other control systems, Advant OCS with
MOD 300 Software does not require the
user to know which subsystem to access
when retrieving information. The Database
Manager and Communications software
work together transparently to access and
update data in the different hardware
subsystems.

When in operation, each Advant Controller
contains Communications and Database
Manager software and a subset of the
Global Database. These three elements
ensure that the controllers communicate
and operate in harmony with other
subsytems connected to the DCN. The
Real-Time Control Applications manipulate
variables read from and written to the
production process through the Field
Communications software.
Advant Controller 41O
The Advant Controller 410 runs the com plete library of MOD 300 control software
and is ideal for small- to medium-sized
applications. The first several slots of the
backplane are occupied by the CPU and
the remaining slots support up to fifteen
Series 100 I/O cards.
Advant Controller 460
The Advant Controller 460 is optionally 1:1
redundant and has a high-speed processor
and backplane that allow many functions
to execute in a single controller module. It
can contain up to three redundant pairs of
modules, thereby reducing the footprint.
With 1:1 redundancy, the backup CPU
runs in parallel with the primary CPU, mir roring and updating the database, so that
in the event of failure, control functions
are transferred to the backup CPU. The
failure is indicated to the operator and the
failed card can be removed and replaced
while the system is operating.

Advant OCS with MOD 300 Software pro vides three powerful control language
packages. Configurable Control Functions,
Taylor Control Language and Taylor
Ladder Logic provide optimal implementa tion approaches in the areas of continuous
control, discrete device control, supervisor
control, sequential and batch control, and
high speed interlock logic control.
Applications developed on other Advant
OCS subsystems can be executed on the
Advant Controller. The ability to mix,
match and execute these control strategies
simultaneously, in common hardware,
offers uncompromising versatility to meet
today’s processing requirements.
Configurable Control Functions
Configurable Control Functions (CCF) is an
easy to configure, function block struc tured control language. It is particularly
powerful in the application of continuous
process control, discrete device handling
and alarm detection.
CCF has an extensive library of functions
and is configured through a menu-driven
software package using a fill-in-the-blank
approach.
Taylor Ladder Logic
Taylor Ladder Logic (TLL) is used for high
speed process interlocking and control
logic. TLL provides industry standard lad der logic control processing, reducing the
need to purchase stand-alone programma ble controllers.
Taylor Control Language
Taylor Control Language (TCL) is a struc tured high-level procedural language. The
programmable flexibility of TCL is ideally
suited for batch control, recipe manage ment, batch reporting, process scheduling,
supervisory control, and process startup
and shutdown.
